Multivariate normal sampling can be wildly irreproducible if you’re not careful. Sometimes more than others. There are eldritch horrors, ill-conditioned matrices, and floating point nightmares in here. Teaching sand to do linear algebra was a mistake

When I recently looked at the state of the art in floating point random number generation, I was surprised to see a common procedure in many programming languages and libraries that is not really a floating-point algorithm: Generate a random integer with bits chosen based on the precision of the format. Convert to floating point. Divide to produce an output between 0 and 1. In code, this looks like: 1 func ( r * Rand ) Float64 () float64 { 2 int64 rand_int = r . Int63n ( 1 << 53 ) 3 return fl

is a reporter focusing on film, TV, and pop culture. Before The Verge, he wrote about comic books, labor, race, and more at io9 and Gizmodo for almost five years. A Shinichirō Watanabe production wouldn’t be complete without an absolute banger of a soundtrack, and his upcoming Adult Swim series Lazarus is no exception. Ahead of Lazarus’s premiere on April 5th, Adult Swim has released three singles from multi-instrumentalist / composer Kamasi Washington, British DJ Bonobo, and producer Floating

Not every large object in space forms part of a solar system. There are some big objects that exist in isolation in space, without either being a star or orbiting one. One of these, SIMP 0136, wanders aimlessly in the Milky Way, about 20 light years away from Earth. It has a mass about 13 times that of Jupiter, and is thought to have the structure and chemical composition of a giant gas planet, though its true characteristics have not yet been determined. Such untethered objects are typically c

Imagine hopping onto a large floatie in a lake or pool, and then trying to move. We’ve all been there—without paddling limbs, wind-catching sails, or a propelling engine, you’re stuck. But what if we could make the water itself move you? An international team of researchers has developed a technique to manipulate water and move floating objects with a level of precision that seems right out of a sci-fi movie. Beyond its inherent cool factor, this research could have practical applications, rang
